If you need to read data from or write data to a Phone Number field, you can do so using our scripting language Lua.

To access this information, make sure the Phone Number field in your form has a slug.

To write your script, simply assign the slug of the field you need to write an answer to to the Phone Number field that you need. See below for an example (where phone_number is the name of the slug you've assigned to your Phone Number field, and calculated_phone_number is where you're putting the Phone Number):

answers.calculated_phone_number = answers.phone_number

Click Save Changes.

When a new form result is created, and the Phone Number field is filled out, your answer will automatically be populated!
